About the project

The Phillip Island Recycled Water Scheme (PIRWS) is an initiative that will provide Class A recycled water via a backbone distribution system to the developing residential areas and surrounding agricultural and commercial businesses on Phillip Island. The PIRWS consists of upgrading a wastewater treatment process from a Class B to a Class A recycled water standard, installation of a buffer storage tank and construction of approximately 12 km of new and upgraded distribution pipe work. The proposal also aims to supply Class A recycled water to existing customers currently accessing Class B recycled water.

Project benefits

This project:

  • reduce potable water use by 194 million litres each year
  • increase Phillip Island's water security to enhance its environmental and tourism reputation and economic sustainability
  • ensure recreational facilities and sporting grounds are watered and maintained at optimum condition to promote community amenity
  • reduce potable water use in new dual pipe (recycled water) estates, and
  • the volume of treated effluent discharged to the ocean.


The project commenced on 9 November 2010 and is scheduled for completion by 30 June 2012.
